- Hot-swappable modules
- °C / °F selectable
About the product
EHRTC-RM2 is a modular rack-type hot runner control system built for demanding production. Every zone module carries its own 3200 W power stage; in case of a fault only the affected module is sent for service, so production keeps running. Temperature-controlled fan cooling, PID Auto-Tune, Ramp/Soft-Start and independent deviation alarms give you full control.

Key features
- Rack system with easily removable modules.
- Fan cooling with speed increasing with temperature.
- Built-in power stage: 3200 W per zone. The power stage sits on each zone module, so only the faulty zone is sent to service and production is not interrupted.
- P.I.D. control; AUTO-TUNE sets the PID parameters automatically.
- STAND-BY: holding temperature and single-key restart.
- Automatic switch to proportional (percentage) operation on thermocouple failure.
- Operation without thermocouple (proportional / percentage mode).
- Dehumidification (Ramp / Soft-Start) to protect heater life.
- Maximum operating temperature 537 °C (999 °F).
- Accuracy of ±0.5 % of full scale.
- Output (power stage) can be switched off with one key without cutting power.
- Adjustable maximum set value limit.
- Automatic fast protection fuse in every module.
- Alarm output on thermocouple break or failure.
- Independent high and low temperature alarm values (deviation alarm).
- Low-temperature alarm can be cancelled at first start-up.
- J type (Fe-CuNi) and K type (NiCr-Ni) thermocouples; selectable in the program.
- °C or °F temperature units.
- Factory reset; OFFSET adjustment (−50 °C … +50 °C).
- Optional cable length and connector configuration.
- 4, 6, 8, 10 and 12 zone options; expandable on customer request.

Frequently asked questions
If one module fails, do I have to send the whole unit?
No. In the RM2 the power stage sits on each zone module. You remove and send only the faulty module; the other zones keep running.
What does Ramp / Soft-Start do?
Heaters absorb moisture when idle for a long time. Soft-Start raises the temperature gradually to drive moisture out safely, extending heater life.
How long does service take?
For all Elotek-made units, technical service takes at most 3 business days including parts supply.
